The School Psychological Services Department includes seven professional staff members. Each of us is licensed by the Texas State Board of Examiners of Psychologists (TSBEP) as a Licensed Specialist in School Psychology (LSSP). As LSSPs, we work with staff to help students be more successful in their academics, behavioral choices, social skills, and emotional management. Working collaboratively with parents and staff, we examine issues that may contribute to student difficulties and then develop and provide interventions and supports specific to each student and situation. We participate in a student's ARD Committee as part of the student's Full and Individual Evaluation (FIE) to complete psychological evaluations and assessments in the areas of autism spectrum disorder, emotional disturbances, attention deficit conditions, functional behavioral assessments (FBA) to determine need for a behavior intervention plan (BIP), and related services counseling assessment to determine the student's need for that related service. Once a disabling condition and education need for services have both been established by the student's ARD committee, we provide, as determined by the ARD process, related services, both on an indirect and direct basis. Indirect psychological services include observation, as well as consultation with parents and staff regarding student behavior and progress in the school setting, including responses to various interventions. Direct psychological services include individual and group counseling, social skills instruction, BIP coaching and crisis intervention.
